'''A tool to validate YAML files against the JSON-Schema schemas.

This wraps Python `jsonschema` module so that YAML schemas can be understood
and YAML data can be validated.

Usage: yaml-jsonschema SCHEMA INPUT1 [INPUT2, ...]

'''


import jsonschema
import yaml

import sys


schema_file = sys.argv[1]
input_files = sys.argv[2:]


with open(schema_file) as f:
    schema = yaml.load(f)


for input_file in input_files:
    with open(input_file) as f:
        data = yaml.load(f)

    try:
        jsonschema.validate(data, schema)
        print("%s: valid" % input_file)
    except jsonschema.ValidationError as e:
        # Print 'e' instead of 'e.message' for more information!
        print("%s: %s" % (input_file, e.message))
